I also have that original problem, ie, loss of control signal warning. Usually, the first I know of it is that it goes RTH. I can cancel, but I wait till it gets closer to do that. It starts warning me of weak signal at about 60m distance. The last flight a few minutes ago also told me I had reached the maximum permitted altitude at 30m! So I will check my settings. Regarding the range problem, I had an experienced DJI person fly it to check, and he said from his experience, that is the best I will get from it. From my experience and reading here, I am sure it will do better than 60m range! All comments are appreciated thanks.
